The impact of the partial government shutdown is visible already in Gettysburg National Military Park, where roads are being closed and areas of the park are off limits to visitors and licensed battlefield guides.

Katie Lawhon, park spokeswoman, said visitors are still welcome at the Visitor Center and Museum, which remains open because it is owned and operated by the Gettysburg Foundation. However, areas of the battlefield, including many roads, will be closed as a result of the shutdown.

A reporter is at Gettysburg National Military Park gathering details.

The government shutdown has not affected care for veterans, as operations at six community based outpatient clinics in the region, including the one in York, will not be interrupted, according to a press release.

Veterans centers in Harrisburg and Lancaster will also stay open, and veterans who have appointments should report for those appointments.

York, PA -

If a partial government shutdown occurs Oct. 1, operations at Gettysburg National Military Park and Eisenhower National Historic Site, as well as at Fort Indiantown Gap would be among the hardest hit in the region.

Katie Lawhon, spokeswoman for Gettysburg National Military Park, said the impact at the park and at Eisenhower National Historic Site would be "pretty drastic."

She said the Eisenhower site and the David Wills House would be closed, as would many of the roads on the Gettysburg battlefield, with the exception of main throughways and those roads with private residences on them.

"People would not be permitted to stroll about the battlefield," Lawhon said, noting that includes licensed battlefield guides, who would need to find creative ways to show visitors the battlefield.

The "bright spot," Lawhon said, is that the Museum & Visitor Center, which is owned and operated by the Gettysburg Foundation and not with federal dollars, would remain open.

While visitors would be permitted entry, there would be no park rangers to answer their questions, as they will be among the roughly 75 permanent full-time employees who would be furloughed. Lawhon said 10 permanent full-time employees designated "essential employees," -- eight of them law enforcement and two of them maintenance workers, would report to work.

At Fort Indiantown Gap, the impact of a government shutdown would be felt at many levels.

Sgt. Matt Jones, public affairs specialist for the Pennsylvania National Guard, said the civilian and military technicians who are not exempt from a furlough would be notified when they report to work on Oct. 1 if a shutdown occurs. He said it's still be determined which technicians would be furloughed, "but it would be a significant amount of our full-time staff," Jones wrote.

"Many soldiers and airmen on temporary work orders would be laid off, and many full-time soldiers and airmen would be furloughed despite it being commonly said that active duty military members would not be impacted by a shutdown," Jones said by email Friday. "Although they are often referred to as civilian employees, military technicians are uniformed soldiers and airmen. These employees are the same who were recently furloughed for six days due to Sequestration."

Jones noted that those classified as active-duty military would remain on duty but could suffer from lapses in salary that would be retroactively paid once the lapse of appropriations ends.

Positions that support key military operations overseas and disaster response would remain, but "administrative, maintenance and training activities could be significantly impacted," Jones wrote. Also, emergency domestic operations which are usually funded by the state and then reimbursed by the federal government, would not be directly affected, Jones said.

The potential impact for other services and programs varies:

--- In a shutdown, mandatory spending programs, such as Social Security, Medicare and Medicaid, would continue, according to an analysis from the Committee for a Responsible Federal Budget. Services considered essential would continue as well.

Multiple York County agencies receive federal funding either directly or through the state, including the nursing home, the Office of Children, Youth and Families, and the Mental Health -- Intellectual and Developmental Disabilities program. York County Prison also receives federal funding to house federal immigration detainees, according to county spokesman Carl Lindquist.

But Lindquist said it's unclear how much of the county's federal funding would be impacted by a shutdown. He said money that flows through state could be backfilled by the state.

Even if all federal money were eliminated, Lindquist said the county has about $9 million in reserves to maintain operations for several weeks."Should some of the major funding streams remain intact, the impact on the County would be significantly lessened," Lindquist said in an email.

--- Normal operations and normal business hours for the U.S. Postal Service would continue, with possible exceptions for post offices that are located inside federal office buildings, said Ray V. Daiutolo Sr., a regional spokesman for the agency. He said the U.S. Postal Service is a self-funded independent agency.

--- The York County Prothonotary's office wouldn't see any interruption in operations or in the services they provide. The only function the office performs that would be influenced by a government shutdown would be the handling of passports, according to Prothonotary Pam Lee.

Passport applications would still be accepted through her office, but the processing facilities that handle the passport applications may be affected by the shutdown, she said.

Shutdown looming: Weekend showdown at the Capitol

WASHINGTON (AP) -- Time running short, the Democratic-controlled Senate passed urgent legislation Friday to avert a government shutdown early next week, and President Barack Obama lectured House Republicans to stop "appeasing the tea party" and quickly follow suit.

Despite the presidential plea -- and the urgings of their own leaders -- House GOP rebels showed no sign of retreat in their drive to use the threat of a shutdown to uproot the nation's three-year-old health care law.

"We now move on to the next stage of this battle," said Sen. Ted Cruz, the Texas Republican who is a face of the "Defund Obamacare" campaign in the Senate and is in close contact with allies in the House.

First effects of a shutdown could show up as early as Tuesday if Congress fails to approve money to keep the government going by the Monday-midnight start of the new fiscal year.

"Think about who you are hurting" if government services are interrupted, the president said at the White House, as House Speaker John Boehner pondered his next move in a fast-unfolding showdown -- not only between Republicans and Democrats but between GOP leaders and conservative insurgents.

Despite Obama's appeal, the Senate-passed measure faces a swift demise in the House at the hands of tea party conservatives who are adamantly opposed to funding that the measure includes for the three-year-old health care law.

The Senate's 54-44 vote was strictly along party lines in favor of the bill, which would keep the government operating routinely through Nov. 15.
